Robust Energy Efficient Multipath Routing Protocol for Wireless Sensor Networks

Energy efficient routing protocol design in the presence of noise and interference is a challenging task in wireless sensor networks (WSNs). In this paper, we present a robust, energy efficient multi-path routing protocol that uses the residual energy and Signal-to-Noise Ratio (SNR) to predict the best next hop node during the route establishment. The new protocol uses multi-path to transmit the data. It splits the message into number of segments of equal size and transmits via multi-path without excessive delay. We studied the performance metrics and compared with other protocols. Simulation results shown that our protocol saves more energy, has lower end to end delay and jitter, and higher packet delivery ratio than other protocols.
